Abstract

L'invention porte sur une sonde de guide d'ondes à plaques espacées pour la mesure diélectrique d'un matériau soumis à un essai. La sonde a une première plaque et une seconde plaque espacée de la première. Il existe un premier ruban d'un premier matériau diélectrique s'étendant entre la première plaque et la seconde plaque au niveau d'un premier côté de la première plaque et de la seconde plaque. Un deuxième ruban d'un second matériau diélectrique s'étend entre la première plaque et la seconde plaque au niveau d'un second côté de la première plaque et de la seconde plaque. Un troisième ruban d'un troisième matériau diélectrique s'étend entre la première plaque et la seconde plaque entre le premier ruban et le deuxième ruban.
